Noob Spearo Podcast listeners are saying;

"This podcast has improved my diving dramatically. I binged listened to all the old episodes over a few weeks and I'm completely caught up now. I take notes on my phone to further research anything the guests or the hosts (Turbo and Shrek) talk about or suggest to do. Over the last 4 months I've gone from a 5 meter pot shot diver to a 12 meter+ diver with over 1:30 dive times and good fish to show for it. All thanks to the information these guys have put out in this podcast. Keep up the great work!" - Kurty

"This is the first podcast I've ever listened to, and I am averaging about 4 episodes a day since that first listen. These guys are awesome and so are there guests! Best motivation to do training! Only problem is I'll run out of episodes soon and have to wait a whole week for a new one..." Pete

"The amount of tip, ideas and laughs I've had from Shrek and Turbo and it has all improved my spearfishing 10 fold. Essential for any spearo, and highly recommend it, you won't regret it! Always hanging for the next episode! Keep it up boys! And while your at it get their book 99 tips to get better at spearfishing! Yew!!!" - Yupz

"Have been listening to Turbo and Shrek for a while now and those weirdos make me come back every time for more.... even though I'm located in Southern California. I guess I'm stoked to hear how people catch their fish all over the world!! Keep it coming boys." - Sebastian

"Guys, honestly, This podcast has been amazing fuel since my surf buddy and I started spearing just over three months ago on the southern california coast. We're pretty much just shore divers right now, but we've been hitting calico bass, yellowtail tuna, and sheepshead by just jumping off the beaches. We're starting to meet some people with boats so we're stoked. My pre-dive tradition is getting amped off a noob spearo podcast before I hop into the water after work. Keep them coming because I just finished listening to the 17th episode and I felt a little post partum depression coming on. I've learned loads from your show and need to keep soaking up the wisdom. Thanks!" - DippnDotts

"I recently got into spearfishing and couldn't believe my luck when I found this podcast after a random search. Not only are Shrek and Turbo incredibly funny and easy to listen too - but the way they have formatted the show is really engaging, informative and interesting. Hearing from Pros and veterans is invaluable to a newb like me and the information from these podcasts alone has made a world of difference to my diving and hunting. So if you're like me and your absolutely loving the sport and simply can't get enough info on and about spearfishing this is the podcast for you! Well done guys, you're keeping me well and truly stoked! sterling job!!" - Stu in Southern California

"Been an avid podcast listener for nearly a decade and this is my first review. This podcast is laid back, informative and absolutely essential for the new spearo. Great list of domestic and international guests. The most dangerous time for a spearo is in those first few months and It's good to know there is a easily accessible resource that I can point my mates to when they are starting out. Cheers shrek and turbo!" - CoxyADF

Interview with Lyndsay Lyon from Ocean Guardian

Today's interview is with Lyndsay Lyon from Ocean Guardian, originally and probably better known as SharkShield! They make a range of products that are designed to make ocean activities safer and to decrease the amount of shark attacks on humans. It works by creating an electrical field that surrounds the diver or surfer that causes a distinct and noticeable reaction in certain types of sharks (namely the ones we humans have trouble with, Great White, Bull Shark, Tiger Shark) and causes them to turn away. Now, making a product that aims to stop shark attacks is a big claim and needs to be backed up by solid evidence and rigorous testing. We had a ton of questions from our community asking the questions that everyone wants to know: Will this stop a Great White from biting me? How close do the sharks need to get for these products to work? Can I trust my life to this?
If you are wondering at all about any of these questions, have a listen to this episode and it will answer all these and more! In the links below are several videos of these products being tested and you can see for yourself just how effective they are.
